Welding GMAW and FCAW-GS Process in synergic mode CV
In synergic mode, the welding voltage is not set by user.
The correct welding voltage will set by the machine’s
software.
This value was recalled on the basis of data (input data)
had been loaded:

Wire Feed Speed, WFS [9].

Note: The list of available programs depends on the power source.
If it is needed, the welding voltage can be adjusted
± 10V by the Right Control [10]. When the Right Control
is rotated, the display will show a positive or negative bar
indicates if the voltage is above or below the ideal
voltage.

Wave Control

Pinch
The 2-Step - 4-Step changes the function of the gun’s
trigger.

2 Step trigger operation turns welding on and off in
direct response to the trigger. Welding process is
performed when the gun’s trigger is pulled.

4-Step mode allows to continue welding, when the
gun’s trigger is released. To stop welding, the gun’s
trigger is pulled again. 4-step mode facilitates to
making long welds.
Note: 4-Step does not work during Spot Welding.

Pinch controls the arc characteristics when short-arc
welding. Increasing Pinch Control greater than 0.0
results in a crisper arc (more spatter) while decreasing
the Pinch Control to less than 0.0 provides a softer arc
(less spatter).

Adjust range: from -10 to +10.

Factory default, Pinch is OFF.
